SPRING MOTOR FOR PUMPS.

SPECIFICATION forming part of Letters Patent; No. 387,736, dated August 14, 1888.

Application filed November 23, 1886. Serial No. 219,707. (No model.)

To all whom it Iii/cry concern:

Be it known that we, CHARLES M. REED, residing near Gonnersville, Fayette county, and WILLIAM G. FRAZEE, residing near Clermont, Marion county, Indiana, have made certain new and useful Improvements in Pump- Driviug Mechanism, a description of which is set forth in the following specification, reference being made to the accompanying drawings, in the several figures of which like letters refer to like parts.

Our invention relates to an imprcvcmentiu mechanism for working ordinary suctionpumps, and will be understood from the following description.

In the drawings, Figure 1 represents a front view of our device. Fig. 2 is a view looking toward the gear mechanism on the line 3 1 Fig. 1, the ends of the shafts being shown in cross-section.

In detail, f is abuse or support, upon which rests a frame-work, f, which provides bearings for a. main shaft, 8, to which is attached a crank, c, and on this shaft is coiled the driving-spring sp, the end of the spring being secured to the stationary rod 1-. This main shaft also carries a driving-pinion, 1, and ratchet-pinion 6, with pawl p and checkspring op. The main pinion 1 engages with a smaller pinion, 5, mounted on a secondary shaft, 8 which carries an intermediate pinion, 2, which engages with a smaller pinion, 3, mounted upon the upper shaft, .9, this latter shaft also carrying a ratchet-wheel, 4, and pawl pforstopping the movement of the mechanism when desired. When the mechanism is working, this pawl is thrown off.

1' is an upper rod which carries the pawl 11.

The crank c is used for winding up the spring, and the elasticity of the spring as it unwinds causes the drivingpiuion 1 to revolve, carrying with it the other pinious, with which it engages directly or indirectly, revolving the upper shaft, 5'. This shaft passes through a boxing connected with a bracket, Dr, and on the end of this shaft is mounted a crank-wheel, cw, to the wristpin of which is connected it crank-rod, or, which is pivoted in a yoke, 3 at the top, and to the outside of this yoke y is pivoted the pitman or pump-rod 1;, having the usual valve working at the bottom of the pumpstock 12s, to the top of which the bracket ?)1' is also connected.

sp is thespout for the discharge of the water.

The mechanism operates as follows: The 55 spring sp being wound up by the crank 0, sets in motion the spur-wheels, the pawl 12 being thrown 0d. The revolution of the shafts opcrates the crank-wheel 010, the crank-rod or, and the pitman p causing it to rise and fall in the pump'stock. The crank-wheel 010 is made of such diameter as to allow a sufficient length of movement to thepumprod 12. When it is desired to stop the mechanism before the spring has run down, the pawl p is thrown over the top of the ratchet 4. The drivingspring may be made strong enough to run as many hours as may be necessary.

By means of this mechanism water can be drawn without the use of either hand or wind power, and the expense of derricks and fans is avoided. If desired, the pump-rod may be connected directly to the wrist-pin of the crank-wheel; but the manner of connection herein shown is preferable.

We are aware that the use of springs to drive cog-wheelsis'not new, and do not broadly claim the same as our invention.

IVhat we do claim, however, and desire to secure by Letters Patent, is the following:

A pump mechanism wherein the suction-rod is driven by means of a pitmau pivoted at one end to a yoke bolted to such suction-rod, at the other to a wrist pin upon a crank-wheel mounted on the end of a shaft supported in hearings in a suitable frame, and in boxiugs connected with a bracket which is connected to the top of the pump stock, the shaft connected with the crank-wheel carrying a pinion which is operated by means of a gear mechan- 9c ism driven by a spring coiled about the main shaft, all combined substantiall y as described.

In witness whereof we have hereunto set our hands, at Indianapolis, Indiana, this 9th day of November, 1886, in the presence of witnesses.
